Search feature is so much fucking better, try it with that google search for xs-scene.
And with a slim box you can keep the mother board and psu where it is.
If you wanted a dvd drive and hard drive is recommend a laptop dvd drive but you could use a normal hard drive.
Mount the laptop dvd above the psu and right side of the motherboard, do the switch, dvd drive ejecting on the other side
or you may be able to have the hdd and dvd drive both on the one side.
